Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 65mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30
The AirTAC SAIJ100X65-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 3927N push force at 0.5 MPa and features a usable travel window of 35 to 65 mm, letting you trim up to 30 mm off the 65 mm nominal stroke during commissioning.
This extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The 25 mm carbon steel rod and M20x1.5 thread handle high side loads, while the rear adjuster acts purely as a mechanical stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30 Is Used
Product Changeovers
Dial in the exact end-stop for varying package sizes on a packaging line without replacing the cylinder or adding external stops.
Machine Setup
Fine-tune the 35-65 mm travel window during initial commissioning to perfect the pressing or lifting position.
Variable End Stops
Adjust the rear stopper to accommodate different material thicknesses in clamping and feeding applications.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (2513N push at 0.5 MPa) is insufficient, but a 125 mm bore is too large. The adjustable stroke is selected over a fixed SAI cylinder when a machine requires fine end-position tuning for product changeovers without swapping hardware.
For ISO 15552 replacement, match the 100 mm bore, 65 mm stroke, 30 mm adjustment, PT tapered port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Since the stroke is under 300 mm, external side-load guides are less critical than on longer strokes, but the adjuster is not a lock—use SAIL or BSAI for load holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-30 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927N and a pull force of 3681N. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw lets you mechanically shorten the effective stroke from the 65 mm nominal down to 35 mm. This allows precise end-position tuning without altering the cylinder mounting.
